Beware the danger of building out isolated network and application network infrastructures in the cloud lest we end up with silos from which it is difficult to escape.   While writing a separate post on the business value of public versus private cloud computing investments I s... (more)

The long, lost application delivery spell compendium has been found! Its once hidden, arcane knowledge is slowly being translated for the good of all web applications. Luckily, you don’t have to be Elminster or Gandalf or to cast this spell ... (more)

Cloud Expo on Ulitzer Brenda Michelson, Principal of Elemental Links, writes "elemental cloud computing" recently tweeted: "100k buys way more public, than private, cloud computing power" which started a short but inspiring conversation on the subject centering around the observ... (more)

SOA & WOA Magazine In the “real world” there are generally accepted standards set for access to a business and its services. One of the most common standards is “No shirt, no shoes, no service.” Folks not meeting this criteria are typically not allowed past the doors of a busine... (more)

Should the next generation management of network and application network devices look and act more like Facebook and Twitter? Infrastructure 2.0 could take us there. Y ou may think I’m kidding and certainly I make this proposal with some amount of humorous intent, but there is s... (more)

SOA in the Cloud on Ulitzer Certainly no one would seriously argue that web applications are fast enough for everyone. SPDY is one suggested solution, but what if we combine MapReduce and SPDY? Could we develop an architectural solution that leverages the best of SPDY without re... (more)

Infrastructure 2.0 Journal on Ulitzer There are many good reasons to go down the virtual infrastructure road. The illusion that it’s cheaper than dedicated hardware solutions is not one of them. I was reading an interesting predictive article on WAN optimization that contends t... (more)

With any luck I am already AFK for a visit with Don’s mother and his family for Thanksgiving. And I’m really (really, I swear) going to be AFK (away from keyboard) for the entire time. Really. I’m serious this time, stop looking at me like that. Ever heard of “pre-publishing?” ... (more)

IT Strategy on Ulitzer Ever wonder why requests coming through proxy-based solutions, particularly load balancers, end up with an IP address other than the real client? It’s not just a network administrator having fun at your expense. SNAT is the question – and the answer. SNAT... (more)

Carrying over the provisioning and capacity planning techniques used in a traditional data center to cloud computing negates the full power of the Force cloud computing. One of the benefits of cloud computing is supposed to be efficiency, particularly in the utilization of compu... (more)

Cloud Security Journal on Ulitzer Sometimes the best answer to a problem is to hit the reset button, but it should probably be the last answer, not the first. My cohort Pete Silva attended the 2009 Cloud Computing and Virtualization Conference & Expo and offered up a summary of o... (more)

Security Journal on Ulitzer How many times have you seen an employee wave on by a customer when the “security device enclosed” in some item – be it DVD, CD, or clothing – sets off the alarm at the doors? Just a few weeks ago I heard one young lady explain the alarm away with “it... (more)

Google’s desire to speed up the web via a new protocol is laudable, but the SPDY protocol would require massive changes across networks to support ArsTechnica had an interesting article on one of Google’s latest projects, a new web protocol designed to replace HTTP called SPDY. S... (more)

Whenever keys, certificates, and PKI enter into a security solution’s architecture the solution almost always becomes overly complex. DNSSEC is no exception, but it doesn’t have to be. DNS plays a role in every application on the Internet. It is the 411 of the Internet, essentia... (more)

One of the biggest threats to data integrity is the introduction of malicious content via SQLi (SQL Injection) attacks. Traditional database access methods don’t provide a lot in the way of validating requests and like HTML the vagaries of SQL allow for myriad ways in which a sta... (more)

Cloud Computing on Ulitzer These three things have a lot more in common than you might think and all three tend to evoke similar levels of frustration. A very real problem women face when shopping is this: no two brands define a size the same. If you usually wear a size 8 in “Bra... (more)

When you look at the success of some very proprietary solutions and the loyalty with which customers defend them, you have to wonder if vendor lock-in is really as bad a thing as we sometimes make it sound. The subtext in the discussions around data portability and interoperabilit... (more)

No, not the kind you do on Facebook when you’re really, really tired but the kind defined as a means to reduce power consumption without affecting application performance or availability by eliminating non-essential processing and networking whenever possible.  An article on “D... (more)

Microsoft has made some fairly substantial changes to the core architecture of Exchange 2010. Given that messaging can only be described as business critical today, it’s no surprise that many new aspects of Exchange 2010 and in particular its new architecture are designed to impr... (more)
